Liebherr SmartMonitoring is a comprehensive solution for documenting and monitoring measurement and operating data, alarm messages and device states. The SmartCoolingHub required for this can be directly connected to this device via the available RS 485 interface.Alarm testing allows you to check whether the alarm system is working correctly (no matter whether it is internal or external). The test has no effect on the performance of the refrigerator. Liebherr has been accumulating experience and research and development in the field of refrigeration for decades, guaranteeing the highest quality of refrigeration appliances By using only the highest class compressors, condensers, evaporators and other components of the cooling system, Liebherr creates energy-saving devices with low operating costs. The built-in temperature alarm informs about deviations above or below the alarm threshold using acoustic and visual signals. to ensure maximum safety of the stored products. All laboratory refrigerators and freezers are tested at Liebherr's state-of-the-art research and development facilities in accordance with the procedure laid down in the EN 60068-3 standard for temperature stability measurement. This includes measuring the temperature at nine different points inside the unit. The primary focus of designing Liebherr appliances was on optimizing energy use and low operating costs. Liebherr only uses natural and environmentally friendly refrigerants R 600a and R 290. In combination with highly efficient compressors, they are extremely efficient and future-proof thanks to their low global warming potential.
